Description

Technical Field

[0001] This utility model relates to the field of spirit levels, and in particular to a spirit level with a distance measuring and angle measuring scale. Background Technology

[0002] In many fields such as construction and decoration, equipment installation, and machining, the level is a core tool for calibrating the horizontal state of objects, and its performance directly affects the accuracy and quality of work. However, traditional levels have significant limitations, mostly focusing on the single function of level calibration, indicating the horizontal position only by emitting a laser beam or using a bubble level. But in actual work scenarios, operators often need to complete multiple tasks simultaneously. For example, when installing brackets on a wall, it is necessary not only to calibrate the horizontal state of the brackets, but also to measure the distance between the brackets and the edge of the wall, and to detect the tilt angle of the wall itself. In this case, relying solely on a traditional level cannot meet the requirements, and it is necessary to carry additional independent tools such as a rangefinder and an angle gauge, which increases the amount of tools carried and requires frequent tool switching during work, significantly prolonging the operation process. This inconvenience of tool switching is particularly prominent when working at heights or in confined spaces, seriously affecting work efficiency. As industries increasingly demand higher efficiency and precision, the traditional multi-tool approach is revealing more drawbacks. Different tools have different design standards and operating logics, requiring operators to master the use and calibration techniques of levels, rangefinders, and angle gauges, increasing the operational barrier. Furthermore, the measurement benchmarks of different tools are difficult to unify completely. For example, if there is a deviation between the calibration baseline of the level and the measurement starting point of the rangefinder, the distance measurement result will not match the level calibration status, thus affecting the accuracy of the installation position. In scenarios with high precision requirements, such as the installation of precision equipment and high-end decoration, this deviation may lead to rework, increasing both operational and time costs.

[0003] Currently, while some multi-functional measuring tools have emerged in the industry, shortcomings remain in structural design and practicality. Some products separate the components for leveling, distance, and angle measurement, resulting in a larger overall size and increased weight, significantly reducing portability and making them inconvenient for operators to hold or carry to different work locations. Some products lack effective protection for the internal electronic components, lacking reliable sealing structures, allowing dust and moisture from the external environment to easily enter, leading to component failure or decreased measurement accuracy and shortening product lifespan. Furthermore, some products have unreasonable layouts of operating controls and display components, requiring operators to frequently adjust hand positions or observation angles to complete operations and read data, resulting in a poor user experience and making it difficult to meet the needs of continuous operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a level with a distance measuring tool and an angle ruler.

[0005] The level instrument with distance measuring and angle ruler provided in this application adopts the following technical solution: A level with a distance measuring device and an angle gauge, comprising: The upper housing is formed as a box and has a receiving chamber with one end open downward. The first outer peripheral surface of the upper housing is provided with a first mounting hole and a second mounting hole that extend through its thickness direction. A ranging chip, wherein the ranging chip is disposed in the receiving chamber and can emit a ranging signal from the receiving chamber through the first mounting hole to complete the distance measurement; A horizontal laser emitter, wherein the horizontal laser emitter is disposed in the receiving chamber and can emit a laser beam from the receiving chamber through the second mounting hole; An angle testing device is provided in the receiving cavity and is equipped with an angle display screen, which is located on the second outer peripheral surface of the upper housing.

[0006] Through the above technical solution, this application uses the housing cavity of the upper shell as the core load-bearing space, integrating the ranging chip, horizontal laser emitter, and angle testing device within it. The first and second mounting holes provide directional channels for the ranging signal and laser beam, respectively, while the angle display screen is exposed on the second outer peripheral surface. This design integrates the three core functions of horizontal calibration, distance measurement, and angle detection, eliminating the need for multiple additional tools and solving the problem of the single function of traditional levels. Furthermore, the orderly layout of each functional component ensures stability and ease of reading during measurement.

[0007] Furthermore, the first outer peripheral surface and the second outer peripheral surface are bent and fixedly connected.

[0008] Through the above technical solution, this application achieves a bent and fixed structure between the first and second outer peripheral surfaces of the upper housing, rather than a planar extension. Optimizing the component layout within the limited housing space, for example, by arranging the ranging, laser emitting components, and angle display at a reasonable angle, avoids interference between functional areas, reduces the overall size, improves comfort during handheld operation, and solves the problem of integrated tools being too large due to planar layouts.

[0009] Furthermore, the level with distance measuring and angle scale also includes: The lower housing is located below the upper housing and is detachably connected to the upper housing to seal the receiving chamber.

[0010] Through the above technical solution, this application forms a sealed structure for the receiving chamber by detachably connecting the lower housing and the upper housing, isolating the internal electronic components from the external environment. This effectively prevents dust and moisture from entering the receiving chamber, protecting precision components such as the ranging chip and laser emitter, and extending the product's service life. At the same time, the detachable design facilitates subsequent inspection and replacement of internal components, solving the defects of poor sealing and difficult maintenance in some integrated tools.

[0011] Furthermore, the lower housing is provided with a mechanical switch, which is located on the same side as the first outer peripheral surface and can control the switching of the ranging chip and the horizontal laser emitter.

[0012] Through the above technical solution, this application sets a mechanical switch on the same side of the lower housing as the first outer peripheral surface, and realizes unified control of the ranging chip and the horizontal laser emitter through circuit connection. This allows operators to perform switching operations on the same side without having to search for scattered control buttons when using the ranging or leveling functions. This simplifies the operation process, lowers the operating threshold, and solves the problem of chaotic layout of integrated tool controls, especially when working at heights or in confined spaces.

[0013] Furthermore, the first mounting hole is located at one end of the first outer peripheral surface, and the second mounting hole is located between the first mounting hole and the mechanical switch.

[0014] Through the above technical solution, this application uses the functional logic of "distance measurement-level calibration-control" to make the operation action form a continuous movement line. For example, when the operator holds the tool, he can first measure the distance through the first mounting hole at the end, then perform laser calibration through the second mounting hole in the middle, and finally operate the switch nearby, avoiding the movement of the hand across areas and improving the smoothness of the operation.

[0015] Furthermore, the level with distance measuring and angle scale also includes a battery assembly disposed in the housing chamber to power the distance measuring chip, the horizontal laser emitter, and the angle testing device.

[0016] Through the above technical solution, this application sets up an independent battery assembly within the housing chamber, providing unified power to the ranging chip, horizontal laser emitter, and angle testing device via internal circuitry. This eliminates the need for an external power source, improves tool portability, and ensures stable power supply to all electrical components, preventing fluctuations in measurement accuracy due to unstable power supply. It also solves the problem of some integrated tools relying on external power and having poor battery life.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This application's level integrates a distance measuring chip, a horizontal laser emitter, and an angle testing device within a housing chamber, combining the three core functions of level calibration, distance measurement, and angle detection into one unit. This completely changes the traditional situation where multiple independent tools need to be carried during operations. Operators no longer need to frequently switch tools, especially when working at heights or in confined spaces. Multiple tasks can be completed with a single tool, significantly shortening the operation process. Simultaneously, all functional components are laid out based on the same housing reference, avoiding accuracy issues caused by measurement reference deviations between different tools. In scenarios such as building decoration and equipment installation, this effectively reduces rework caused by inconsistent references, adapts to high-precision operation requirements, and reduces time and cost losses.

[0018] 2. This application breaks through the limitations of traditional planar layouts by using a bending and fixing structure on the first and second outer peripheral surfaces of the upper shell. While ensuring the reasonable installation of each functional component, it significantly reduces the overall volume and weight of the tool, improves the comfort and portability of handheld operation, and solves the problem of some integrated tools being too large and having poor portability. The detachable and sealed connection between the lower and upper shells can effectively prevent external dust and moisture from entering the containment chamber, providing reliable protection for internal precision electronic components such as the ranging chip and laser emitter, and extending the product's service life. At the same time, the detachable design facilitates subsequent inspection and replacement of internal components, reduces maintenance difficulty, and avoids maintenance inconvenience caused by the enclosed structure.

[0019] 3. This application features a mechanical switch on the same side as the first outer peripheral surface, and the first mounting hole, the second mounting hole, and the mechanical switch are arranged according to the functional logic of "distance measurement-level calibration-control". This allows the operator to form a continuous operation path when holding the tool, and can complete function switching and control without adjusting hand posture across areas. It is especially suitable for personnel who are not familiar with multi-tool operation, thus lowering the operating threshold. The independent battery pack in the housing provides unified power supply for each power-consuming component, freeing it from the constraints of external power supply and improving the applicability of the tool in power-free scenarios. At the same time, the stable power output can avoid measurement accuracy deviation caused by power supply fluctuations, ensuring functional stability during continuous operation and solving the defects of some integrated tools that rely on external power supply and have poor battery life.

[0022] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0023] This application discloses a level with a distance measuring tool and an angle ruler.

[0024] Reference Figure 1-2 A level with a distance measuring and angle scale includes an upper housing 1, which is integrally formed as a cuboid box structure. An internal receiving chamber with one end opening downwards is opened along the length direction. The inner wall of the receiving chamber is provided with multiple protruding buckle seats and threaded posts for fixing the internal functional components. The outer peripheral surface of the upper housing 1 is divided into a first outer peripheral surface 11 and a second outer peripheral surface 14, which are bent and fixedly connected at 90°. The bending connection adopts a rounded transition treatment, which not only enhances the structural strength of the housing, but also avoids sharp corners from scratching the operator.

[0025] On the first outer peripheral surface 11, a first mounting hole 12 and a second mounting hole 13 are provided through it along its thickness direction: the first mounting hole 12 is located at the upper end of the first outer peripheral surface 11, and its diameter is adapted to the signal transmitting end of the ranging chip 2. An annular dustproof pad is attached to the inner edge of the hole; the second mounting hole 13 is located below the first mounting hole 12, and the size of the second mounting hole 13 is adapted to the size of the laser transmitting end of the horizontal laser emitter 3. A transparent acrylic protective sheet is embedded in the inner side of the hole, which can block dust from entering and does not affect laser penetration; the central axis of both holes is perpendicular to the first outer peripheral surface 11, ensuring that the ranging signal and the laser beam can be stably emitted in the horizontal direction.

[0026] Inside the housing chamber, the ranging chip 2 is secured to the latch seat on the left side of the housing chamber via a snap-fit ​​at its bottom. The signal window is also tightly fitted with the dustproof pad of the first mounting hole 12, ensuring that the ranging signal emitted by the ranging chip 2 can completely pass through the first mounting hole 12, avoiding signal loss. Below the ranging chip 2, a horizontal laser emitter 3 is screwed to the threaded post in the center of the housing chamber via a retaining ring on its outer periphery. Its laser emitting end is aligned with the acrylic protective sheet of the second mounting hole 13, and the center of the emitting end is coaxial with the center of the second mounting hole 13, ensuring that the laser beam is emitted horizontally, meeting the requirements for horizontal calibration.

[0027] An angle testing device 4 is also provided on the side of the receiving chamber near the second outer peripheral surface 14. The angle testing device 4 is equipped with an angle sensor and is connected to the angle display screen through a wire. The angle sensor is fixed on the buckle seat on the right side of the receiving chamber, near the second outer peripheral surface 14. The angle display screen adopts an embedded structure, and its edge is fixed to the reserved mounting groove of the second outer peripheral surface 14 with sealant. The surface of the display screen is flush with the second outer peripheral surface 14, which avoids the protruding structure from affecting portability and makes it easy for operators to read the angle data intuitively from above.

[0028] The cavity also houses a battery assembly 6, which includes a battery compartment and a lithium battery. The battery compartment is a rectangular box structure with a power supply interface on the top and a lithium battery installed inside. The power supply interface of the lithium battery is connected to the power supply terminals of the ranging chip 2, the horizontal laser emitter 3, and the angle testing device 4 through wires to provide stable power to each component.

[0029] Below the upper housing 1, there is a lower housing 5, which is a cuboid cover structure adapted to the upper housing 1. Its edges are provided with buckles and threaded holes corresponding to the edges of the openings of the accommodating chambers of the upper housing 1. The lower housing 5 is detachably connected to the upper housing 1 by engaging the buckles and locking with screws. At the mating surface between the lower housing 5 and the upper housing 1, an elastic sealing ring is embedded, which completely covers the mating gap to form a sealing structure and prevent external dust and moisture from entering the accommodating chamber. The lower housing 5 is provided with a mechanical switch 51, which has an anti-slip press cap on the outside and is internally connected to the power supply circuit of the ranging chip 2 and the horizontal laser emitter 3 through wires. The mechanical switch 51 is embedded on the front of the lower housing 5 and is located on the lower side of the lower housing 5 near the second mounting hole 13.

[0030] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
